CompTIA A+ Core 1 (220-1201) — Question 121

A user returns from a trip and discovers a computer that is connected to the LAN times out intermittently. Upon investigation, a technician finds the RJ45 pin is not properly terminated. Which of the following networking tools is most appropriate to fix the issue?

Answer options

Correct answer: D

Explanation

The correct tool to address an improperly terminated RJ45 connector is a crimper, as it is specifically designed to attach connectors to cables securely. A toner probe is used for tracing cables, a cable tester checks for connectivity issues, and a punchdown tool is for terminating wires into patch panels or keystones, but not for fixing connectors.
